STOP AND WASTE OR DRAIN CCCK.

Specification of Letters Patent.

, *atented Sept. 23, 1913.

Application tiled May 3, 1912. Serial No. 695,004.

To atl 'who/m, t may concern Be it known that I, l/ViLLIaM E. Bonne, a citizen of the United States, residing at Lorain, in the county ot Lorain and State of Ohio, have invented new and useful Improvements in Stop and Vaste or Drain Cocks, ot which the following is a specification.

rlhis invention relates to new and useful improvements in stop and waste 4or drain cocks for use as faucets as well as for application to hydrants and to any other appliances that act on the stop and waste prineiple.

The primary object of the invention is to construct a stop and waste or drain cock wherein each of the functions may be etfeeted independently ot' the other so that the stop may be completely closed bet'ore any waste is possible and thereby intercept the water in the supply pipe from communication with the waste outletduring the operation of the same and also to set up an instant outlet tor the waste or drainage at the moment that the stop is closed, and, furthermore, to cut oil all possible escape of water through the waste or drainage ports or outlets when the stop is opened.

The improved stop and waste or drain coclcin addition to the ordinary essential elements of devices of this class, and ineluding a valve head, comprises what may be termed a compoundvalve stem composed 01:' parts one of which, at least, is movable relatively to the other and operable by reason of temporary frictional association under certain adjustable conditions to unitedly move in opening and closing the valve head so that when the latter is opened water will be prevented from escaping through the waste or drainage outlets and when the said head is closed it is caused to firmly engage its seat prior to the release of the waste or drainage outlets.

The invention also consists in the details of construction and arrangement oit the several parts which will be more fully hereinafter described and claimed.

In the drawing: Figure 1 is a longitudinal vertical section of a stop and Waste or drainage cock embodying the features of the invention and showing the parts of the stem in a position to occlude the waste or drainage outlets and the main valve or valve head closed against its seat; Fig. 2 is a similaiview showing the main valve or valve head closed and the one member oil the compound valve stem Ishifted longitiulinally relatively to the other member to open the waste or drainage outlets or ports t'or the egress of waste or drain water through the valve stem. Fig'. 3 is a similar view illust ating the valve or valve 'head open and the waste or drainage outlets or ports closed by the stem to prevent the water passing through the body oit' the valve from escaping through the said outlets or ports, a key of particular form being shown applied to the stem in dotted lines. Fig. 4 is a transverse vertical section through the body oi the key shown by dotted lines in Fig. 3.

The numeral 5 designates the body of the cock having a partition G interrupting the passage therethrough and also provided with an inlet 7 and an outlet 8. The partition G is formed with an opening 9 around which is a valve seat 10, and in axial alinement `with the said valve seat the body 5 has a A lateral cylindrical extension 11 interiorly screw-threaded as at 12 to adjustably receive a correspondingly screw-threaded plunger 18 carrying a valve head 15. The valve head 15 has a valve disk 1G mounted on the lower end thereof and shown as held in place by a screw 17, the said valve disk being of suitable material to set up a water-tight cngagemcnt with the valve scat 10 when the valve head 15 is adjusted to cause the disk 16 to tightly engage the said seat. lhe operating means for the plunger 1?, and its valve head 15 consists ot' a compound stem which in part forms the outlet ttor the waste or drainage and comprises a screw-threaded shank 1S of suitable length and a tubular member 19 through which the said shank extends and provided with an operating handle 20. The tubular n'iember 19 is lully open at its upper end around the shank 1S as at 21 and its lower end has a screw-threaded bore 2Q through which the shank 1S projects, the lower end oit' the member 19 being also provided with an outlet port 23 tally open to a chamber @i termed in the lateral cxtension 11 above the plunger 13. 'l he bore ol the tubular member 19 has a materially greater diameter than the diameter ot the screw-thremled shank 18 so that a clear outlet annular passage is formed in the tubular member around the said shank. The plunger 13 has a port or duct Q5 extending therethrough and communicating with the chamber 2li and with the outlet extremity of the these conditions solely as the egress means :tor the waste or drainage. ln opening the valve head 15 the member' 19 is first adjusted upwardly from the position shown by lliig. E2 until the upper tlatend thercotI engages the `gasket 31 to set up a trietional liiinding relatively to the latter and then the shank '14S may be adjusted with the member 19 by continuing to turn the handle 2O to raise the plunger 13 within the lateral extension 11 and elevate the valve head 15 from the seat 1t), as shown by Fig. 3. By first adjusting the member 19 in an upward direction, the port Q3 in the lower end thereot is closed by passing upwardly into the bore or opening ot the coupling nut 3S, and he said port remains in closed condition during the passage oit the water or other liquid into the body 5 and through the partition G and outlet 8, and hence no leakage will .result through the member 10, though some ot' the water may pass through and abo-ve the plunger 13.

It will be understood that the :improved stop and waste or drainage cock is particularly adapted tor use in -freezing temperature to cut ott the How oit' water, tor instance, from a system ot pipes and permit the water ren'iaining in said pipes to run outwardly through the eock to overcome the disadvantages and injury to the pipe system incident to the water remaining in the pipes freezing and oeeluding all bursting ot the latter. In seasons or temperatures when :freezing ot the water will not occur it is unnecessary to drain the cock, and the improved device by the construction hereinbet'ore explained may be readily adjusted to close the waste or drainage outlets, as shown by Fig. 1, without interfering with the opening and closing movements oit the valve head 15. It will also be observed that the essential element or member ot the improved cock, consisting ot the part 19 of the stem, may be adjusted or moved independently et the valve head 15 and does not require chambering or channeling of the plunger or valve head in order to render it operative and the cost ot manuilaeture is thereby materially reduced and the association oit the several parts oit the cock is lvery much simplified. It tound necessary substitution for worn parts oit the cock by other devices oit a similar character may be readily etfected at a minimized expense and thus prolong the li't'e ot the cock at a comparatively small cost. Vlt will be understood that the disk 1G, packing or washers Bland gasket 31 may be constructed ot any material adapted for the purpose and may bc readily replaced when worn and rendered unfit for further use. By having the extremity Q7 of the shank 1S provided with a screw-thread differing from that ot' the shank body, the cap nut 2S will be prevented from working loose by the operation et the said shank 1S and member 19 relatively to each other and said cap will be held in one position for positive engagement with the upper flattened end 32 which constitutes an annular tace with the gasket 31 to establish trictional binding between the upper end oit the member 1) and the shank 1S through the said cap nut 28.

lhe parts oit thel stop cock may be modilied in their proportions and dimensions to aeeommodate di ll'erent applications thereof, and, -turtliern'iore, the device as a whole may be disposed as shown in the drawing or in any ot her position.
